Figure 6.Untargeted HPLC-MS analysis of algae extracts. Principal component analysis (PCA) (A) of algae extracts measured using the ESI+ and ESI- acquisition mode. Underlying peak areas are log10 transformed and pareto-scaled. (B, C) LC-ToF-MS intensities of 7-phloroeckol (B) and caffeic acid quinone (C). Intensities are displayed as the mean of triplicate injections (duplicate injections for Saccorhiza).
